Watt-hour Meter Testing,
This original mission of NIST continues to be important, particularly as new metering technology (e.g., solid state) and power quality issues (e.g., harmonics) raise new concerns about the accuracy and impact of meters. NIST both performs tests of meters and maintains an active R&D program, enabling them to conduct special tests beyond the standard ones. Also, the Measurement Assurance Program evaluates the performance of a customer's (manufacturer's) own energy measuring systems.
Calibration of secondary standards is done for manufacturers, utilities and PUCs on a fee-for-service basis.
